10.2 Reading and Programming the Regulation Parameters
The regulation parameters are the most frequently accessed control parameters (P0 to P9) (see Table below).
The measurement parameters are the actual values from the sensors connected to the controller (d1 to d9).

P0 25…100 70 % Maximum production
P1 2.0…19.9 5.0 % rH Humidity differential
P2 (P3)…100 100 % rH High humidity alarm threshold Accessible only in
P3 0…(P2) 0 % rH Low humidity alarm threshold automatic regulation (A0=2 or 3)
P4 0…100 1 minutes Alarm delay
P5 2…100 10 % rH Dehumidification dead zone Accessible only with
P6 2.0…19.9 5.0 % rH Dehumidification differential dehumidification option (see b1)
P7 (St)…100 100 % rH Supply sensor set point Accessible only in stand-alone regulation
P8 2.0…19.9 5.0 % rH Supply sensor differential with supply air sensor (A0=3)
P9 0…100 100 % rH Supply sensor high threshold alarm
